The emissivity of a given surface is the measure of its ability to emit radiation energy in
comparison to a blackbody at the same temperature. The emissivity of a surface varies between
zero and one. This is a property that measures how much a surface behaves as a blackbody. The
emissivity of a real surface varies as a function of the surface temperature, the wavelength, and
the direction of the emitted radiation.
Reflectivity is the amount of radiant energy reflected off a surface and it is related to surface
material.
these characteristics impact visual augmentation systems. because by detecting thermal radiation
emitted by a body position of that body can be located. similarly reflectivity effect is used in
visual glint phenomenon.
these two techniques are used in euipment used by army to detect and locate position of enemy
